Changes in fuel need to be proportionate with changes in airflow. The Lex AFM only works with injectors flowing around 550 (unless you have other means of adjusting fueling). 660cc/min = too much; 440cc/min = too little; 200cc/min = way too little; 600cc/min = still too much. The 550's aren't quite perfect either, the mod relies on closed loop operation to trim low load fueling.... but it's close enough.
